Description
Technical field
Present invention relates in general to a kind of method and mobile telephone terminal that can merge the telephone service on the heterogeneous network (that is, circuit-switched network and packet switched data network).It pays close attention to all portable terminals that can be used for phone, that is to say: cell-phone, smart phone and the personal computer that comprises telephony interface.
Background technology
In enterprise, provide complicated voice service by the uniform communication server to the employees of this enterprise, for example unified catalogue research, communication log, instant message transmission, phone and instant message transmit online (presence) and for example call out keep, switch back and forth (backand forth), meeting, calling transfer, visit central directory, according to the voice service of name dialing, call log, voice mail or the like.These services are all available for the fixed-line phone terminal, but only are that part is available for these mobile telephone terminals in the time of still outside portable terminal is in this business location.
Especially, uniform communication server provides some basic service to traditional GSM cell-phone, and activation and deactivation etc. are shifted in for example meeting, calling transfer, the consulting of commercial voice mail, two calling, commercial affairs.These basic services are to activate by the DTMF sign indicating number that sends via the GSM telephone-switching network.The DTMF sign indicating number has been represented the action of user on 12 dial keies of phone respectively.These yards are merely able to transmit 12 symbols and can not be used for data are carried out reverse transmission from the server to the terminal, because mobile telephone terminal can not comprise dtmf decoder usually.
Wish by add more complicated service (for example, commercial catalogue consulting, the consulting of commercial call log, according to name dialing, instant message transmit, phone is online or the like conventionally offers the service of solidus terminal by unified communication) expand these services.The service of these complexity can not activate by the Dual Tone Multifrequency sign indicating number that sends via the GSM circuit-switched network, because it needs more signaling data and two-way transmission.The service of these complexity is by via mobile packet switched data network (for example 3G network (GPRS, UMTS, HSDPA etc.) or high data rate WLAN (WiFi, WiMAX etc.) or the signaling data of the packet switching network that upgrades sends realization.
At present the voice application solution at hand mobile telephone is deployed on public land walking circuit switching network (only having basic service) or the public land packet switched data network (having the complex services except that basic service), but never is deployed in simultaneously on two types the network.That is to say signaling or be carried on circuit-switched network (for example GSM) or be carried on the packet switched data network (GPRS, UMTS, HSDPA etc.), and never be carried on the two simultaneously.
Wish that alternately uses two types network, thereby in the telephone service of complexity for providing complicated telephone service to the terminal use in possible, and, when the telephone service (not having the network coverage) of complexity can not be provided, only provide basic service as alternative scheme.
Service can generate signaling data simultaneously on circuit-switched network and packet data network.Yet in this case, two kinds of signaling types all should be processed, though it is asynchronous transmission.For example, when setting up calling, voice application should be waited for the circuit-switched call signaling, to think that it serves as actual active that voice link is arranged.On the other hand, the packet data network signaling might be lost, and this depends on the network coverage.Therefore be necessary when service is activated the signaling data from two types network is carried out synchronously, and when only there being one or several circuit-switched networks that standby mode is provided for available the time.
Like this, just need provide a kind of technical scheme to come when service is activated the signaling data from two types network is carried out synchronously.3GPP community has developed a kind of solution that supported by internet multimedia subsystem (IMS).Yet this solution has two shortcomings: nowadays IMS does not obtain widespread deployment, and therefore can not dispose in enterprise owing to it is too expensive yet.
Document WO 2006/137762 has been described the terminal in a kind of mobile communication system, it is arranged to a receiving terminal and transmits first Media Stream and second Media Stream (being respectively applied for video and voice), this first Media Stream and second Media Stream are separated from each other and transmit, but side by side transmit to small part.This first Media Stream and this second Media Stream and second end to end time delay relevant with first end to end time delay are relevant.This first end to end time delay is greater than this second end to end time delay.
This terminal further comprises:
-control device, configuration are used for presenting first Media Stream in end again from transmission delay a period of time of first Media Stream, and this time is depended on the time difference between first end to end time delay and second end to end time delay;
-and the device that is used for the estimating peer-to-peer time delay, its configuration is used to estimate first end to end time delay and second end to end time delay.
As described below described first end to end time delay is estimated:
Very first time when-record has asked the packet of answer to be sent to receiving terminal to it;
-record receives second time of answer from receiving terminal;
-from second time, deduct the very first time;
-alternatively, from resulting subtraction result, deducting the possible stand-by period, waiting time begins until answer is sent it back the time that this terminal is waited for from receiving the packet that is transmitted for this receiving terminal;
-with the result of subtraction divided by two, and;
-with the result of division calculation and the current buffer delay addition in the receiving terminal, in receiving terminal, the transmission terminal is measured and sent it to this buffer delay.
The solution that this is known also is not suitable for carrying out synchronously indicating about first data and second data of the incident of same call, and reason is: because rare, these incidents do not generate continuous data flow, as voice or video.Therefore can not estimate all time migrations once.The time interval between the recovery incident accurately is for unimportant about the incident of calling out.What is more important is correctly recovered for the perception of incident order, because this all is vital for foundation or call release and every other call service.
The objective of the invention is to solve this stationary problem by simple mode.

Embodiment
Fig. 1 shows the execution mode 1 according to telephone terminal of the present invention, and it transmits and receive signaling data simultaneously on circuit-switched network 3 and packet switched data network 4.This terminal is connected to the base station 2 that belongs to circuit-switched network 3 and packet switched data network 4.In one of present embodiment substitutes, to realizing being connected of packet switched data network and circuit-switched network by two discrete base stations.This terminal 1 is submitted communication event 6 and the while used instead in basic service with enterprise's uniform communication server 7 at circuit-switched network 3 and is submitted other communication events 5 of using instead in complex services at packet switched data network 4.
This server 7 is traditional uniform communication server.
Fig. 2 has functionally represented an execution mode according to telephone terminal of the present invention.It comprises:
-software module 21 is used for voice application, comprises signal processor 22;
-software module 24 is used to receive the communication event that arrives by circuit-switched network 3, and software module 25, is used to receive the communication event that arrives by packet switched data network 4;
On the one hand, for example meeting, switch back and forth and complicated voice service such as transfer all is to serve and trigger via passing through web that packet switched data network 4 transmits.All communication events relevant with communications status also transmit to portable terminal by packet switched data network 4.On the other hand, for example utilize the GSM signaling on circuit-switched network 3, to set up voice channel.
The purpose of signaling memory 23 is these two kinds of signaling flows synchronously.This sets up particularly necessary for voice communications: by communication event incoming terminal before indicating the GSM signaling that enters calling of packet switched data network 4 transmission.On behalf of the GSM signaling of efficient voice call setup, therefore, just be necessary to postpone first communication event arrive with wait.Simultaneously, the communication event that arrives by packet switched data network 4 can bring added value to voice application by for example giving information such as caller's name, caller's phone number caller instant messaging status.
Realize synchronously by means of the memory of between two communication event receivers 24 and 25, sharing 23.If formerly first communication event that receives via packet switched data network 4 must just can obtain handling, just be written into memory 23 when then this first incident is received after the second communication incident that receives via the GSM circuit-switched network is received.When GSM signaling incoming terminal, whether events corresponding receiver 25 inspection has corresponding incident Already in the memory 23.It finds first incident and then sends it to voice application 21 in memory 23 signal processor 22.
Communication event receiver 24-25 is responsible for analyzing from the incident of packet switched data network 4 and circuit-switched network 5 respectively.The incident that is received by incident receiver 24 and 25 can directly be forwarded to signal processor 22, perhaps can temporarily be stored in the memory 23, is shared to be other incident receivers.Incident receiver 24 and 25 is checked the content in the memories 23 and the incident that is stored in this memory 23 is analyzed.Thereby the incident receiver considers to determine that to the type of each incident and the current state of communication directly forwarding incident still is that its temporary transient storage is received up to another incident.
Usually, via the communication event of packet switched data network than via the faster arrival of the communication event of circuit-switched network.But also opposite situation can take place, thereby at this moment shared storage 23 is just utilized in the same way by incident receiver 24 and 25 incident is carried out synchronously.
For example, receiving the gsm communication incident can trigger the packet switched data network of transmitting formerly to signal processor 22 4 that passes through and receive and be stored in communication event in the signaling memory 23.
In other cases, the communication event that is stored in the memory 23 can prevent that communication event receiver 25 is forwarded to signal processor 22 with the GSM incident that receives.
Below description mobile telephone terminal according to the present invention is set up call, management second enters three situations of calling out and then finishing first calling under the situation that does not have the packet switched data network availability.
Fig. 3 shows the signaling flow that mobile telephone terminal wherein according to the present invention is set up the example of call:
It is available that-voice application 21 detects packet switched data network;
The signal processor 22 of-voice application 21 sends the web request to set up audio call (step 31) to uniform communication server 7;
-server 7 is by circuit-switched network 3 callback terminals 1 and send application affairs by packet switched data network 4 simultaneously and started with indication and spread out of calling (step 32).Communication event receiver 24 writes shared storage 23 with this incident.
-communication event receiver 25 receives the gsm communication incident (step 33) that enters that calling has arrived that enters of indicating from circuit-switched network 3.
25 pairs of received incidents of-communication event receiver analyze and detect this enter the gsm communication incident in fact corresponding spread out of calling.(that is, do not allow the user know and set up calling) (step 34) replied in this calling with being mourned in silence.
-circuit-switched network 3 sends the gsm communication incident of setting up audio call of indicating.Communication event receiver 25 is not forwarded to this incident voice application to prevent setting up audio call (step 35) mistakenly too early before far-end (remote peer) is answered this calling.
-simultaneously, server 7 sends communication event (warning) by packet switched data network 4, is indicating and is attempting to set up audio call with far-end.This communication event is forwarded to signal processor 22 and indicates callee's terminal just in ring (step 36) with the user to terminal.
-when far-end answered the call, server 7 sends was indicating audio call to be active (that is, having set up) communication event (step 37).This incident is forwarded to the signal processor 22 in the voice application 21, and it is indicating this calling to be established to the user.
-then voice application 21 is handled the calling of having set up.
Fig. 4 shows this mobile telephone terminal wherein at this first signaling flow that receives the example of second call during calling out.In order to simplify example, suppose other GSM incidents that the GSM calling has been set up and can not have been received and calling newly is associated:
-server 7 attempts to set up second audio call (step 41).Communications event handler 24 all received communication events are forwarded to signal processor 22.
-answer user's request, voice application 21 utilizations send until the web of server 7 service signaling by packet switched data network 4 and answer second calling and first calling is placed maintenance (step 42).
-server 7 is called out first and is placed the voice flow (step 43) that keeps and activate second calling.
-server 7 sends is indicating second audio call to be active (that is, having set up) communication event (step 44).This incident is forwarded to the signal processor 22 in the voice application 21, and this incident is set up to user's indicating call.
-server 7 sends is indicating the maintained communication event of first audio call (step 45).This incident is forwarded to the signal processor 22 in the voice application 21, and this incident indicates first calling to be in maintenance now to the user.
-state in the end, voice application 22 is handled two audio calls, and one of them is held.
Fig. 5 shows this mobile telephone terminal wherein and switches from second call and get back to first and call out and the signaling flow of the example that disappeared of the covering of packet switched data network wherein.Therefore signaling will be carried by circuit-switched network 3 fully:
It is no longer available that-voice application 21 detects packet switched data network 4.
-answer user's request, voice application 22 sends the DTMF sign indicating number to discharge active calling (promptly second calling out) (step 51) by circuit-switched network 3.The serviced device 7 of these DTMF sign indicating numbers receives and carries out decipher.It discharges second and calls out.
-communication event receiver 25 is simulated corresponding to the incident of described second release of calling out and is sent it to signal processor 22 (step 52).
-communication event receiver 25 is simulated corresponding to the incident of described first activation of calling out and is sent it to signal processor 22 (step 53).
-voice application 21 sends the DTMF sign indicating number by circuit-switched network 3 and calls out (step 54) to server 7 to activate first again.The serviced device 7 of these DTMF sign indicating numbers receives and carries out decipher.It activates first again and calls out.This final step 54 is optional.In other embodiments, server directly is interpreted as the release of this active call to place the activation of the calling of maintenance in step 51.There is not step 54 in this case.
